1. No Touch response when display touched
• Swap display panels with known good panel. If touch works,
problem with display flex or IC (Go to 2). If still not working,
problem with main board (Go to 3).
2. Display module issue
• Check Touch flex for any damage
• Ensure DC power is at ZIF pin 9 for 3.2VDC and pins 11&12 for
1.8VDC
• Verify Reset signal is high on Touch ZIF pin 4, IRQ is high on ZIF
pin 7
• I2C Data and I2C Clock at 1.8VDC
• When touching panel and moving finger, INT should toggle low,
I2C data and clk will toggle.
